About This Item

The intention of this standard is to establish a framework to measure the efficiency of PWM HVAC Blower Controllers and Brushless DC Motor Controllers and define a usage based overall efficiency. This result can then be used by vehicle OEMs to demonstrate compliance towards requirements or benchmarks established by regulatory agencies. Legislation has been introduced that provides credits for the use of emission reduction technologies. One such technology is the use of a Pulse Width Modulated (PWM) HVAC Blower Controller (together with a brushed DC motor) or a Brushless DC controller (with Brushless DC motor) in place of traditional HVAC Blower Controllers such as resistors or Linear Power Modules. A uniform standard does not exist to evaluate the efficiency of such controllers and estimate the impact towards emissions and qualify for credit with the legislative bodies. Latest revision includes minor corrections and clarifications.
